Application filed August 29, 1910. Serial No. 579,380.

To all whom it may concern: j

Be it known that I, HERMAN L. Kn'r'rnn, a citizen of the United States,residing at Hamilton, Butler county, Ohio, have invented certain new anduseful Improvements in Paper-Making Machines, of which the following isa specification.

This invention pertains to Fourdrinier paper-making machines and relatesto improvements upon the construction of the Fourdrinier franie setforth in my United States Patent No. 654,651, of July 31st, 1900.

v The present improvements relate to the construction of the shake-railtrusses, to the construction of the shake-legs, to the mounting of thebreast-yell, and to the construction of the breast-roll}truck-mechanism.

The invention will be readily understood from the following descriptiontaken in connection with the accompanying drawings in which Figure 1, isa front elevation of one of the shake-rail trusses: Fig. 2, a sideelevation of the head portion of the same in conjunction with the shaltelegand the breast-roll truck: Fig. 3, a vertical section of one of theshakelegs, in the plane of lines a of Figs. 4 and 5: Fig. 4, anelevation of one of the shake-legs as viewed from the right in Fig. 2:Fig. 5, .a side elevation of the breast-roll truckmechanism as viewedfrom the right in Fig. 2: Fig. ,6, a side view of the guide-pipe of thetruck-mechanism. The various figures of the drawings involve a diversityof scales. As both sides of the machine are to be alike the showing anddescription will be general structure, under the free end of the'shake-rail: 4, the vertical pivot uniting the free end of the shake-railto the shake-leg: 5, a strong bracket rigidly secured to the lowersurface of the shake-rail at its free end, this bracket presenting avertical surbracket: 7, a truss-bar disposed below the shake-rail andhaving its two ends rigidly,

secured to the vertical faces of the brackets 8, struts firmly connectedwith the shake-rail vibrating independently of each other.

The brackets at the ends of the shake-rail of-themselves endow the endsof the shakerail with very reat vertical stiffness and the truss-barcompletes the trussing of the shakerail, the inner vertical members ofthe brackets forming vertical strut-members at the ends of thetruss-bar. The struts 8, further stiffen the structure but are notneeded on very short machines. The two brackets being locatcd'at theends of the shake-bar close to the two supports of the bar, at pivots 2and 4, effectually guard against deflection ofthc bar at points near itsend. Inpractice I construct the bracket of steel castings, and Iconstruct the truss bar'of cast iron of inverted channel section. Theends of the t-russ-' bar abut against the inwardly presenting faces ofthe brackets and are there solidly bolted, the ends of the truss-barresting on hooks projecting inwardly from the flat inner faces of thebrackets.

Proceeding with the drawings :11, indicates a pair of hearings in acommon line length-wise of the machine, these bearings being secured tothe mill floor below the free end of the shake-rail, the two bearingsbeing, preferably, cast in one piece: 12, a vertical tube disposedbetween the two bearings and forming the lower member of the shakeleg:13, bushings in the upper and lower ends of the tube: 1.4, trunnionsprojecting from the tube and journaled in the bearings, the tubeprojecting some distance below the bearings, and freely through suitablefioor-openings prouicled for them: 15, a screw mounted for verticalsliding motion in the tube, the periphery of the screw nicely fittingthe bushings of the tube: 16, a nut threaded upon the screw and restingupon the upper end of the tube: 17, a worm-gear carried by the nut:

18, a worm-shaft journaled in suitable bearings projecting from thetube: 19, a worm carried by the worm-shaft and engaging the wormsgear:20, a hand-wheel on'the wormshaft, by means of which the nut can beturned and the screw raised and lowered in the tube: 21, a'spmcket-wheel'on the shaft to provide for .a chain transmitting theworm motion to the worm at the opposite shake-leg, as in my earlierpatent: 22, a shake-leg head-casting having a large gap open,preferably, toward the tail end of-the shake-rail, this casting beingbifurcated at its upper end to receive the pivot-bearing 9 of theshake-rail, the casting 22 forming the end. of the rigid breast rollframe extending across the machine: 23, a pair of separated fore andaft'downwardly open bearings in the base of the head-castingz-2a,trunnions projecting fore and aft from the head ,of the less than thedistance between the two trunnion bearings a pivot engaging the pivotbearing 9 of the shake-rail and passing through the two side members ofthe'bi- ZO-furcated upper end of the head castingz 2ti,

a breast-rollbearing disposed in the gap of thehead-casting, thisbearing comprising about half of the circleof the bearing'so as 5breast-roll bearing: and 29, the general level of the mill floor.

Y The vibrating motion of the shake-rail is; I provided for by theoscillation of the tube and screw on tru-nnions 14 and by the rocking ofthe screw-head trunnions in the head casting, the head-casting beingquite disconnected from the tube except through the medium of the-screwand its trunnions. The head ofthe screw, being less in width than thedistance between trunnion bearings 23 permits of a trifle of endwiseshifting of the head-casting on the screw trunnions as inciden't to thevibrating motion of the shakerail, pivots 4. and 25 connecting theshakemil with the head casting also providing for theslight changes inangular relationship between the shake-rail and head-casting.

The breast-roll journal ,has. its bearing forwardly and downwardlyinbearing 26 so as to properly take the strain of the making wire, thebearing being held in this normal Working position by bolt 28. 1 Whenthe breast roll is' to be removed, bolt 28 is first displaced, thuspermitting the bearing to swing downwardly and forwardly on its pivot27. But the relationship of pivot 27 to thesegmental bearing is suchthat when the bearing thus swings downwardly, sofas to brin the centerof gravity of the breastroll un er the pivots 27, the hearings willscrew and engaging the bearings 23, the 15 head of the screw being of a'width a trifle "no'attention need be given to still have such completehooking engagement with the breast-roll journals as to hold thebreast-roll suspended. Then, by lifting the roll and swinging thebearing forwardly and upwardly, the roll may be removed forwardly anddownwardly so as to be withdrawn endwise from .the' machine. And,similarly, when the roll is to be placed in the machine, its journalsare passed into the gaps in the head-castings and then the'bea r ingsareswung into hooking engagement below the journals, after which thebearings are pushed rearwardly and the bolts 28 applied. This system oftemporarily supporting the breast-roll by bearings under free suspensionis manifestly available in 1na-; chines gapped to the rear as well as tomachines having the breast-roll frame-gapped forwardly as in theillustration."

It is to be particularly observed that the mounting of the breast-rollis such that all of the strains and strengths are in a single verticalline, that is to say, the axes of the axes of the breastroll journal andscrew 15 and pivot 4 coincide and intersect I trunnions 24 and 14,- Asubstantial adherv the breast-roll in the plane'of the general verticalaxis of the shake-legsis found in practice to. give a very much betterbalance ence to the plan of disposing the axis of. I

and easy working of parts than when the 1 roll is some distance to thefront or rear of the axis of the shake-legs.

If the breast-roll, instead-of being disposed substantially below pivot25, be any material distance to the rear or to the front of the verticalplane of that pivot the effect, as the shake-rails are'raised andlowered, would be to slightly alter the relationship between themaking-wire and the slices and thus disturb the delicate sliceadjustment. In the present construction not only may the wire be raisedand lowered while the machine is in'operation, but the slices by reasonof such adjustment.

Proceeding with the drawings, and giving particular attention to Figs. 5and 6r-- :30, indicates a'l'ow floor stand disposed below the rear oneof thetwo shake-rails 1, this floor stand presenting upwardly a. pair ofangular projections, the pair being arranged fore and aft of themachine: 31, a

rails and carry the breast-roll when being placed and removed: 34;,wooden bearing blocks in the trucks to receive the breastroll journals:35, a third floor-stand temporarily placed at some distance from thefront of the'machine and in line with the other floor stands: 36, a pairof track-rails similar to the other rails, supported by floor stands 31and 37, a light pipe having a length somewhat greater than from theoutside of floor-stands 30 to the outside of floor-stand 31: 38, notchescut in this pipe to freely engage over the intermediate portions offloor-stands 30 and 31: 39, an elbow projecting rigidly inward and,preferably, from the rear of the shake-leg head-casting 22: 40, aframe-bar to-be rigidly connected with the two elbows, this frame-barand the two head-castings forming the breast-roll frame which isarticulated to the shake-rails and to the leg screws as has'beendescribed: 41, a' feather dis posed in the groove in tube 12 and bearingagainst a flattened side of screw 15, this feather being pressed to thescrew by means of side-screws: 42, the bridge-piece connecting the twofloor-bearings 11: and

43, a lug projecting from the inner side of 'tube 12 and adapted toengage the bridgepiece and liinit the inward rocking of the tube uponits trunnions.

The vibrating motion is to begotten to i the general structure by anysuitable means, but my preference is to employ a lever projectingoutwardly from the base of the rear shake-legs, as in my earlier patent.The length of the shake-legs, and the consequentv inclination ordeclination of the making-wire may be adjusted at both sides of themachine simultaneously by manipulating the mechanism giving rotation tothe nuts 16, and without interrupting the ru'nning of the machine. Thisvertical adjustment of the shake-legs requires that the screw shallslide in its'tube, and the character of the shaking motion is such as totend to beget looseness at this fit and to be itself more or lessseriously effected by the looseness. Renewable bushings 13 provide forkeeping this fit in pretty good conditiombut perfect rigidity of the fitis secured by means of the feather and set-screws, the latter beingloosened up a when the adjustment is to be made.

The height of the floor-stands of the truck-mechanism i .t Q, be such asto support the track-rails 32in position over the lower portion of themaking-wire when the wire is down. Under normal conditions nothing of.the truck-mechanism will be present except floor-stands 30 and 31.

lVhen-putting the breast-roll .in place, pipe 3'7 is to be placed onfloor-stands 30 and 31, and this pipe being a light afi'air can beeasily handled without danger of injury to the costly wire. The pipe,when in position on the floor-stand, is to be over the lower member ofthe making-wire. One of the rails'32 is now to be slid in on this pipeas a safe supporting guide, the angular form of the track well lendingitself to 005perative engagement with the guide-pipe, and 'a man at therear of the machine may then help the front man to place the trackrailon projections of the floor-stands, and the same with the othertrack-rail 32. Temporary floor-stand 35 and front track-rails as are nowto be placed in position and the trucks placed. on the front rails, andthe breast-roll placed on the trucks. The trucks with the breast-rollare now to be run in under the machine-frame, in position between theupper and lower members of the making- 7 wire. The breast-roll bearings,hanging 1n free vsuspension, are to be raised andthe breast-roll is tobe raised and moved rearwardly so that the bearings may be swung underthe breast-roll journals, thus supporting the breast-roll by suspension.The bolt 28 is now to be applied, clamping the breast-roll bearingfirmly to the breastroll frame and drawing the breast-roll to itsfarthest I'GEIIWflIClPOSltiOD. It is to be observed that by this systemthe makingwire does not, in the operation of getting the 95 breast-rollto place, require to ,be stretched rearwardly beyond its working point.When the breast-roll is lifted'free of the trucks they may be run out tothe front of the machine and all of the truck-mechanism re- 100 movedexcept the permanent floor-stands 30 and 31, and in this operation ofremoval the guide-pipe 37 again serves in protecting the wire while thecomparatively heavy tlllCk-I'flllS are being removed.

In erecting the Fourdrinier frame, or at any time when it is seriouslydismantled and disconnected from the shake-im arting mechanism, there isa tendency or the shake-leg system to topple on the floor-trun- 110nions. In the present case the lugs 43 engag- 'ing the bridges of thefloor-bearings limit this toppling motion, thereby preventing damagingtwisting strains of the shake-rails and guarding a ainst other damagelikely to result from t5: unrestrained side swinging of the structure.
